An internal anterior fixation system for treatment of vertebral burst fractures includes an elongated plate having longitudinal axis which includes integral superior, inferior and bridge portions. The superior and inferior portions are provided for fixation to corresponding vertebrae while the bridge portion spanning between the portions over the affected vertebra. The superior portion includes a pair of generally parallel elongated slots therethrough each having scallops on for receiving bone fixation screws or bolts. The inferior portion includes a pair of openings through which fixation screws or bolts extend. The slots in the superior portion allow for compression or distraction of the intermediate vertebral region. The openings in the inferior portion are oriented at an oblique angle relative to the axis of the plate to provide a quadrilateral fixation construct. The bridge portion has a width significantly less than the width of the superior and inferior fixation portions. |
